September 11, 2020, marks the 19th anniversary of the most brazen and deadly terrorist attacks on American soil. The unprovoked act of violence, planned by Islamic extremist organization Al Qaeda, killed 2,977 innocent people and changed life as we knew it forever....

When the United States formally entered World War II — the six-year-long global conflict that began in 1939 with Nazi Germany's attack on Poland — in 1941, millions of brave Americans helped to fight for the cause. Among them was New Orleans resident Lawrence Brooks, who served the country for five years as a soldier in the US Army's 91st Engineer Battalion. Fortunately for us, Brooks, who will celebrate his 111th birthday on September 12, 2020, is still around to share his exciting encounters....

A perfectly-preserved silver dollar, which set a new world record for coin sales when it auctioned for $10,016,875 in 2013, is back on the market, and experts believe it might fetch even more this time! The rare "Flowing Hair" coin, which features a portrait of Lady Liberty on one side and an eagle on the other, will be sold to the highest bidder by Legend Auctions on October 8, 2020, at The Venetian Hotel in Las Vegas....

Andean Condors, which weigh between 20 to 30 pounds (9 to 13 kilograms) and boast a wingspan of more than 10 feet, are one of the world's heaviest and largest flying birds. Yet the majestic vultures, which spend their days circling the Andes mountains and nearby Pacific coasts of western South America in search of carcasses, manage to stay afloat for hours....

Invented by French teenager Louis Braille in 1824, braille has enabled millions of visually impaired kids worldwide to learn to read and write. However, the system of raised dots, representing individual alphabet and numbers, can be complicated for younger students to grasp. As a result, parents and educators are increasingly shunning the tactile literacy system, which is taught using special textbooks, in favor of online learning programs. Now, Denmark's LEGO Group hopes to reverse the trend with the help of braille bricks that allow children to learn through play....

Marvel fans and movie enthusiasts worldwide are mourning the sudden death of Hollywood star Chadwick Boseman. The 43-year-old actor, best known for his portrayal of T'Challa — the king and protector of the fictional African nation of Wakanda in Black Panther — passed away on August 28, 2020, after a four year battle with colon cancer. The news came as a shock to most people since the intensely private Boseman, who was diagnosed at stage 3 cancer in 2016 — the year King T'Challa debuted in Captain America: Civil War — never spoke publicly about his illness....

Scientists from the University of Texas at Austin have finally solved the mystery of a massive fossil that has been sitting unlabeled and unidentified at a Chilean museum for almost a decade. The relic, which resembles a deflated football, is the largest-known soft-shelled egg from a marine reptile that inhabited Earth over 66 million years ago — about the time of the mass animal extinction event. Measuring more than 11 by 7 inches it is also the second-largest egg belonging to any known animal, behind only the now-extinct elephant bird....

Every summer, the Israel Antiquities Authority (IAA) invites teenage volunteers to work alongside archeologists at one of several dig sites across the country. The program, designed to provide the youth with an authentic archeology experience and to help them connect with Israel's history, usually results in the discovery of ancient tools or pottery. However, two teenagers at an excavation site in Yavneh, south of Tel Aviv, struck gold — literally— when they unearthed a clay jar filled with gold coins on August 18, 2020....

Bei Bei's 2019 departure from the Smithsonian's National Zoo, to join the giant panda breeding program in China's Wolong Nature Reserve, left a big void for fans. What made the loss of the adorable cub even more poignant was the belief that his mother, Mei Xiang, was too old to have more offspring. However, on August 21, 2020, the 22-year-old proved experts wrong by giving birth to a healthy cub....

To the novice baker, the classic teardrop-shaped baking chip, created by Nestle in 1941, may appear like the perfect mechanism to introduce specks of chocolate to cookies and other treats. However, experts assert that the chip's dense bottom, which blocks the oven heat to retain some shape, prevents the consumer from fully experiencing the luxurious feel and taste of the melted chocolate. Now, Tesla engineer Remy Labesque has rectified the decades-old design flaw with a stylish, pyramid-shaped version that purportedly melts in your mouth, instead of sticking to the teeth like traditional chocolate chips....

North America's relatively calm summer weather ended last week when a powerful derecho swept across the Midwest — from South Dakota to Ohio — on August 10, 2020, and a rare firenado struck Northern California on August 15, 2020. If you are like most people, you have probably never heard of either of the rare natural phenomena. Here is a brief explanation of the incredible extreme weather events....

While astronomers have discovered evidence of thousands of exoplanets, obtaining direct images of the distant worlds has always been a challenge. That's because the planets tend to huddle close to the star they orbit and often get concealed by their star's dazzling light. Of the handful of images captured, most are of a single planet orbiting a Sun-like star. The only two multi-planet systems photographed feature brown dwarfs, or "failed stars," which are radically different in nature from the Sun. Now, an international team of scientists may have finally captured a young, Sun-like star with two giant Jupiter and Saturn-like planets in orbit....

The San Francisco Zoo's annual "March of the Penguins," to celebrate the graduation of their Magellanic penguin chicks from "fish school," is usually attended by hundreds of cheering fans. Unfortunately, COVID-19 restrictions forced this year's ceremony, held on August 8, 2020, to be limited to a handful of lucky guests and officials. However, the lack of fanfare did not appear to bother the six adorable graduates proudly waddling over to their permanent home on Penguin Island....

On August 11, 2020, presumptive Democratic presidential nominee Joe Biden made history by announcing California Senator Kamala Harris as his running mate for the upcoming election. Harris, who is the daughter of immigrants from Jamaica and India, is the first African American woman on a major party ticket and only the fourth woman in US history to run for vice president. She is also the first person of Asian descent to appear on a presidential ticket....

Stephen Wamukota, a nine-year-old from Mukwa village in Western Kenya, is making headlines worldwide for his ingenious hand washing machine. The young boy came up with the idea after watching village residents, who do not have easy access to running water, struggle to find an effective way to wash their hands to avoid spreading and contracting COVID-19....

Summer 2020 has been exciting for stargazers. They have been treated to a once-in-a-lifetime visit from comet NEOWISE and had the rare opportunity to observe five planets and a full moon simultaneously, among other celestial events. Now, to top it all off, come the Perseids — the biggest and most spectacular meteor showers of the year....

SpaceX's first-ever passenger flight to the International Space Station (ISS) ended successfully on August 2, 2020, when Crew Dragon Endeavour splashed into the Gulf of Mexico off the coast of Pensacola, Florida. After a series of safety checks, the recovery teams unlocked the capsule's hatch and quickly whisked the spacecraft's precious cargo — NASA astronauts Bob Behnken and Doug Hurley — to shore. During their total 64 days in space, the astronaut duo completed 1,024 orbits around Earth and traveled 27,147,284 miles....

The lack of clues left behind by ancient Americans has made it difficult for researchers to pinpoint precisely when humans first arrived on the continent. However, it has always been believed to be about 13,000 years ago, just as the world was thawing from the last ice age. Now, evidence from the Chiquihuite Cave in Zacatecas, Central Mexico, seems to suggest that prehistoric humans may have been living in North America as early as 30,000 years ago....

Male birds typically sing the same tunes as the rest of their species because an unrecognizable song defeats the two primary reasons for their crooning — to establish and defend their territory and to attract mates. While the songs, which are passed down from generation to generation, may vary slightly by region, any new compositions are typically limited to the local environment. However, for reasons unknown to scientists, white-throated sparrows across Canada are abandoning their classic song for a catchy new tune "written" by their peers in British Columbia....

Scattered across the ocean bed, and often hidden from the human eye, are hundreds, or perhaps even thousands, of "blue holes." The massive underwater sinkholes, which host a diverse biological community — ranging from coral to sponges to sharks to sea turtles — were formed thousands of years ago when groundwater dissolved karst, a type of porous limestone rock found on ocean floors....

American civil rights leader and U.S. Representative John Lewis (D-GA) passed away on July 17, 2020, following a seven-month battle with pancreatic cancer. The 80-year-old dedicated his life to building what he called "The Beloved Community" in America — first as a civil rights leader and then as a lawmaker advocating, for reforms on issues from gun control to health care....

Over the years, there have been numerous attempts to create "glow-in-the-dark" plants. However, none of the approaches — which included infusing plants with nanoparticles of the luciferins and enzymes needed for the phenomenon to occur, or incorporating them with bacterial bioluminescence genes – proved feasible....

On July 18, 2020, about 150 Paris residents settled inside 38 electric boats floating on the Seine river to enjoy a free screening of Le Grand Bain — a 2018 comedy about a group of middle-aged men forming a synchronized swim team. The city's first "Cinema sur L'Eau," or "Cinema on Water," was organized by MK2 Cinemas to celebrate the June 22 reopening of the country's movie theaters, which had been shuttered since mid-March to stem the rapid spread of the novel coronavirus....

Even those not normally interested in astronomy will find it hard to resist NEOWISE, the brightest comet to grace our skies since the 1997 appearance of Comet Hale-Bopp. The spectacular cosmic snowball of frozen gas, rock, and dust has been visible to those willing to wake up before dawn since early July. However, it has now risen high in the evening skies and can be viewed with the unaided eye by even the most casual stargazer....
